Alfa Romeo Investigations

Low Pressure Fuel Pump Assembly Failure

On January 8, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE24003) to assess allegations of loss of motive power resulting from low-pressure fuel pump failures in certain MY 2017–2019 Alfa Romeo Giulia vehicles.  The subject vehicles are equipped with 2.0L 4-cylinder and 2.9L 6-cylinder turbocharged engines and manufactured by Fiat Chrysler Automobiles US LLC (FCA US).  Reports received by ODI alleged stall and loss of motive power at speeds above 25 mph, with several reporting that the condition resulted in permanent disablement of the vehicle.  Many reports described recurrence of the failure after an initial repair. During the investigation, ODI determined that the subject vehicles were equipped with fuel delivery pumps supplied by Vitesco Technologies Germany GmbH.  ODI also confirmed that MY 2018–2019 Alfa Romeo Stelvio vehicles were equipped with the same pump.  ODI’s analysis identified an elevated failure rate associated with the original pumps installed in the subject vehicles.  The failure mode involves interruption of fuel flow, resulting in fuel starvation and an unexpected loss of motive power, typically with little to no
